Indian restaurants cook a whack of different curries to order. Ever wonder how they do it? For sure they don’t have 25 curries simmering away in the kitchen. Nobody can run a restaurant like that.

It’s cooked to order and it’s done using Indian restaurant curry base. Curry base is at the heart of every Indian restaurant kitchen. Giant pots of it simmering away. Once I heard about it I started asking waiters. I met kitchen staff. I even talked about it with a chef or two. I was on the inside. Now you are too…

Never heard of curry base? Not surprising. For the longest time it was a closely guarded secret. Even now, Indian restaurant curry base recipes are carefully guarded secrets. A hint of carrot – ooohhhh. A bit of cabbage – aaahhh. A green pepper – ssshhhh. But that’s how it’s done.

It’s a bit ridiculous. In it’s simplest form it’s just a lot of boiled onions with some spices and oil. Seriously. Cook it up and it tastes like a weak curry onion soup. Nothing to it. Not particularly tasty. But when you layer the Indian restaurant technique on top it’s magic. Something wonderful happens to that insipid onion soup. It caramelizes. The depth of flavour is – well it’s restaurant quality.

It’s not hard. It’s just a matter of rolling up your sleeves and getting it done. Chop some onions. Add some water and some seasoning and boil. Puree. Boil some more. Done.

One thing to note. Indian restaurant curries are big on oil. This recipe is about as low as you can go on the oil. Don’t use less. It just won’t work. Indian restaurant curry is a lot of things but low calorie it is not.

Indian restaurant curry base is the foundation for restaurant style curry. It's what makes Indian restaurant curry what it is.
Recipe type: side
Cuisine: indian
Serves: 12
  • 8 large onions - about 2.5 lbs peeled weight
  • 6-8 whole cloves of garlic
  • 1½ Tbsp coarsely chopped ginger
  • 1½ Tbsp cumin powder
  • 1½ Tbsp coriander powder
  • 1½ tsp turmeric
  • 1½ tsp salt
  • 12-15 fresh cilantro stalks with leaves - roots removed
  • 1 cup vegetable oil
  • 12 cups boiling water
  • 1 15 oz tin diced tomatoes
Step 1
  1. Bring the water to a boil (a kettle works well for this).
  2. Quarter the onions and then break them apart into petals (roughly - two or three petals per quarter)
  3. Combine all ingredients except tomatoes, bring to a gentle boil and simmer one hour. Use a big pot!
  4. Add tomatoes, stir and simmer an additional 20 minutes
  5. Let cool slightly. Blend to smooth consistency. Make sure you remove the centre cap from the blender lid and cover the hole with a cloth or you will be cleaning the ceiling. Alternately you can use an immersion blender.
Step 2
  1. Wipe out the pot and return pureed curry base and simmer until the oil separates out - this can take an hour or more. Stir the oil back into the base. At this point you can portion out the base into 2 cup portions and freeze if desired.
If you don't want to wait an hour or more during step 2, you can safely stop after 30 minutes - it's not the end of the world.

Don't worry if you get a bit of "scum" on the surface. Just mix it back in.

This recipe makes enough for 10-12 curries (restaurant size portions)

Use within a week or freeze in 2 cup portions (one curry worth)

  1. Fantastic post. This will be going into my little recipe book. I would love to do more Indian style curries and I’m excited you have a selection for me to pick from. Do you have any suggestions on what spices to layer on top of this curry base?

    • Joyce – this is the first in a series of blogs on how to cook real Indian restaurant curry (well second I guess as I posted garlic ginger paste recently). In the coming weeks I will publish posts on spice mixes, techniques and some restaurant favourite curry recipes.

  2. Great post! Thank you so much for taking the time to write this! I was wondering how long can the curry base sit in the freezer before use it? And if I can cut the recipe in half, since I don’t plan to make 12 curries within a week?

    • You are very welcome. Thank you for reading it. I think you could halve the recipe without any problem. In a freezer, I think it would probably last for a couple months although I never seem to manage to keep it around that long.
